Abstract: 579,425. Turbine and like rotors and blading. BELL, F. R., JUDSON, C. A., PETRIE, J. A., and HAWORTH, L. Oct. 6, 1943, No. 16403. [Class 110 (iii)] A turbine or air-compressor is built up of a number of rings 14 pressed end to end and providing annular grooves between them in which the blade roots 11 are clamped. The rings are held between inwardly turned conical end pieces 16 which screw on to a tube 23. The threads at the ends are of opposite hands and the rotor is tightened up'by turning the tube 23 by means of teeth 24. The end pieces and one end of the tube engage splines 25, 26 on the shaft 17. Centrifugal force in the rotor may be taken by rings 18 to a, degree determined by the selected fit of the rings. The rings 18 may be of a material different from that of the rings 14 so that, for example, a larger proportion of the stresses is taken by the rings 18 under normal operating conditions. The rings 14 may abut on the whole of their end surfaces or on spaced areas. Driving keys may be fitted in the cutaway spaces or, the rings 14 may not touch, the whole of the axial force being used to clamp the blade roots and in such case the rings 14 have interengaging dogs on their end surfaces. The surfaces 13 of the rings 14 may be suitably tapered to increase the frictional hold on the blade roots.

Filed: 1959-06-21
Abstract: 936,649. Semi-conductor devices. RANKXEROX Ltd. June 21, 1959, No. 16536/59. Class 37. A process of electrophotography comprises the steps of uniformly charging in the dark a thin insulating layer having an underlying semi-conductor layer on a conductive backing, and then exposing the plate to a pattern of radiation while an electric field is superimposed through the layer. The insulating layer 11 may be 20 to 200Á. thick and may consist of an insulator or high resistivity (10<SP>13</SP>) semi-conductor such as amorphous selenium. Oxygen, arsenic or tellurium may be added to the selenium or the selenium may be alloyed with As 2 S 3 . Suitable selenium may also be obtained by evaporation from a crucible containing selenium and iron filings. Cadmium sulphide and cadmium selenide may be used for layer 11. The semi-conductor layer 12 should be between 0.1 and 5Á thick and may consist of metallic selenium or selenium with halogen as impurity. Arsenic, tellurium, silver, antimony and bismuth may be added to the selenium. The conductive backing 13 may consist of brass, tin-oxide coated glass magnesium, aluminiurn, beryllium, copper, lead, gold or silver. Two semi-conductor layers forming a PN junction may be provided between the insulating layer and the conductive backing. If desired, the insulating layer 11 or backing 13 may be transparent to enable radiation from either direction to reach the semi-conductor layer 12. Theroretical aspects are discussed, including the amplifying effect of the PN hook arrangement and it is pointed out that the layers should be of materials having long carrier lifetimes. Reference has been directed by the Comptroller to Specification 812,917.

Abstract: 348,410. Safety razors. IRELAND, W. F., 55, Bath Road, Wolverhampton. May 29, 1930, No. 16585. [Class 30.] In a clamped blade type safety razor the sides 6 of the upper surface of the clamping plate 1 are inclined at between 40‹ and 60‹ to a plane containing its edges 7, and its inner face is transversely curved. The guard teeth are similarly inclined at 8 so as to lie in the same plane as the sides 6 when the plates are clamped without a blade. The remaining parts 10 of the guard teeth which underlie the blade may be plane as shown or curved to a lesser radius than that of the blade when clamped. The clamping plate 1 is flat-topped and carries the central clamping screw and the guard may carry the aligning pins. The bottoms of the guard teeth may be sloped off at an acute angle, shown dotted, to facilitate escape of lather. Both the guard and clamping plates may be cast, rolled or pressmoulded in a metallic or a non-metallic mouldable material such as a moulding powder of the phenol formaldehyde condensation or other synthetic resin type. In the moulded construction, the clamping plate 1 may be moulded around the clamping screw. When made of metal, the surfaces 6, 8 may be machined together at one operation. According to the Provisional Specification the middle part of the guard plate may be curved to a greater radius than its edges which correspond to the curvature of the blade when clamped. The clamping screw may then be slackened so that the middle of the blade lies against the guard and gives a closer shave.

Abstract: 569,340. Moulding articles from thermoplastic sheet material.BYERS, J. S., HAMBLIN, F. T., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 29, 1941, No. 16718. [Class 87 (ii)] In moulding an article from a sheet of thermoplastic material the sheet is made plastic, prior to shaping, either (a) by heating the sheet and controlling the heating so as to give a predetermined differential plasticity thereto, or (b) by heating the sheet and then so cooling it as to give a - predetermined differential plasticity thereto. (a) A sheet 10 is clamped in a flange 9 to which is connected a flexible pipe 8 through which air under pressure can be forced, and a bank of infra-red heating lamps 3 is disposed over the sheet, the bank being adjustable vertically by means of counterweights 5. The lamps 3 may be energized individually or in small groups; for example; the outermost lamps may be energized and the central lamps left dead, so that the rim of the sheet is heated to a greater degree than the centre. When the sheet has been sufficiently heated the flange 9 is swung around so that the sheet covers the opening into a matrix 12, the sheet is forced into the matrix by compressed air and the moulded article is allowed to cool and then removed from the matrix. The article has a substantially uniform thickness. In modifications, (1) the sheet is clamped between rings, differentially heated, and forced over a patrix by applying hand-pressure to the rings, (2) the sheet is laid upon felt or brown paper, differentially heated and shaped in a matrix or over a patrix, (3) the heating may be effected by hanging the sheet vertically between two banks of infra-red lamps, (4) the sheet 10 may be blown into hemispherical or spherical shape without the use of a matrix, (5) the lamps 3 may be placed in more than one plane at different distances from the sheet 10, or may be located in a plane forming a dihedral angle with the plane of the sheet. (b) The sheet is heated in an oven, and air is blown on to the heated sheet through unevenly - spaced holes in a plate P. By the invention, articles of uniform or non-uniform thickness may be produced. The thermoplastic material may be cellulose acetate or polymerized methyl methacrylate.

Title: A process for producing aromatic ª-acylaminoalkyl and aminoalkyl compounds
IPC: C07D/
Filed: 1960-05-12
Abstract: Acylamino compounds which contain the group: -CH(R).NH.CO.R1 directly attached to an aromatic or heterocyclic ring are made by reacting an alkylidene bisamide: <FORM:0951940/C2/1> with the appropriate cyclic compound having a substitutable hydrogen atom in the ring, in the presence of a phosphorus oxyhalide.  In the above formulae, R is a hydrogen atom, a lower alkyl group or a phenyl group and R1 is a lower alkyl group or a hydrogen atom.  The cyclic compound may have one or more hydroxy, methoxy, nitro, carboxylic or acetylamino substituents. The acylamino compounds, made by the above process, may be hydrolysed to obtain methylamines substituted by cyclic groups. In Example 1, a mixture of phenol, N,N1-methylene bis-acetamide, chloroform and phosphorus oxychloride is refluxed for 4 hours on a water-bath. The mixture is poured into water, and neutralized with sodium bicarbonate.  The organic layer is separated, and distilled to remove chloroform. The residue is distilled under reduced pressure to isolate N-(2-hydroxybenzyl)-acetamide and N-(4-hydroxybenzyl)-acetamide. The former amide is hydrolysed with sodium hydroxide solution to obtain 2-hydroxybenzylamine.  Example 3 describes the preparation of N-(2-hydroxy-5-nitro-benzyl)-acetamide, and its subsequent hydrolysis to 2-hydroxy-5-nitrobenzylamine.  In Example 5, methylene bis-acetamide is reacted with N-2-tolylacetamide, in the presence of phosphorus oxychloride, to give N,N1-diacetyl-2-amino-5-aminomethyl-toluene. Example 8 describes the preparation of N-acetyl-5-amino-methyl-8-hydroxyquinoline. Example 9 describes the preparation of N-acetyl-5-methylamino-2-hydroxy-benzoic acid, and its subsequent hydrolysis to 2-hydroxy-5-aminomethyl-benzoic acid. In Examples 12 and 13, methylene bis-propion-amide and methylene bis-formamide, respectively, are reacted with 2, 4-xylenol to give N-(2-hydroxy-3, 5-dimethylbenzyl)-propionamide and N-(2-hydroxy-3, 5-dimethylbenzyl)-formamide. In Example 14, benzylidene bis-acetamide is reacted with 2, 4-xylenol to give N-(2-hydroxy-3, 5 - dimethyldiphenylmethyl) - acetamide. Example 16 describes the preparation of N-(2-hydroxy-5-nitrodiphenylmethyl)-acetamide, and its subsequent hydrolysis to 2-hydroxy-5-nitro-diphenylmethylamine Examples 7, 10 and 18 describe the preparation of compounds having a benzene ring with a methoxy substituent. Examples 4 and 15 describe the preparation of compounds with a naphthalene ring.
